发明名称 RECORDING AND REPRODUCING DEVICE FOR BROADCAST CONTENTS
摘要 PURPOSE:To enjoy properly the desired broadcast programs by recording plural broadcast wave signals to a recording medium such as a magnetic tape, etc. after modulating them by a frequency modulator, etc. and multiplexing and then demodulating selectively each broadcast wave signal in a reproduction mode. CONSTITUTION:Each bradcast wave received through an antenna 1 is tuned, and the frequencies are modulated by frequency modulators 3a-3d of center frequencies fa-fd for each output of tuners 2a-2d. These modulated broadcast wave signals are multiplexed through BPFs 4a-4d, and these multiplexed signals are supplied to a magnetic head 9 and recorded on a track of a magnetic tape 10 serving as a recording medium. At the same time, the signals obtained by the head 9 are separated into each band and demodulated by demodulators 13a-13d to be turned into original broadcast wave signals. These signals are selected by a selection switch 14 to obtain a desired braodcast wave.
